How to remove "jumps" of trackpoints in Camera tracking when moving them?

So my answer is solved now I think. After reading this I know, that the "jumps" the lines are doing are caused by moving them. Because if you move one its speed increases immensely. And if the lines indicate the speed of a tracker, they will go up too. That's causing the jumps. 

The other points where the red and the green line is connected. A new Trackpoint was created.
